Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic suitable as a massage cosmetic.

  In recent years, it is an era of stress overload, and various stress mitigation measures have been devised. Among them, esthetics are attracting particular attention because they not only act on the whole body and relieve stress, but also recover the effects of stress on the body. Recent advances in esthetics extend not only to scientific analysis of treatment methods, but also to the development of cosmetic media suitable for treatment. In particular, in the case of esthetics, since the degree of warmth at the time of treatment has a great influence on the success rate, a cosmetic medium that gives a favorable warmth stimulus has been developed. That is, it has been pointed out that the esthetic effect is impaired because the sympathetic nerve is stimulated when a cold feeling is felt when cosmetics as a treatment medium are placed on the skin at the start of esthetic. For the purpose of preventing such sympathetic nerve stimulation, the above-mentioned warmth-imparting cosmetic medium has been developed. As such cosmetics, for example, those using the heat of hydration of polyhydric alcohols such as glycerin exist. (For example, refer to Patent Document 1 and Patent Document 2) However, in such a warming-imparting cosmetic, there are not a few cases where it is difficult to say that the warming is sufficiently imparted, and the warming is imparted. In some cases, the irritation of parabens is exacerbated, and it is difficult to say that the desired effect of the preparation is always obtained. By improving this point, the antiseptic effect was replaced with an antibacterial polyhydric alcohol such as 1,2-pentanediol, and the warmth imparting effect impaired by the addition of the antibacterial polyhydric alcohol was improved by menthol or glyceryl monomenthyl ether. A technology for supplementing with the addition of has been developed (for example, see Patent Document 3). However, by employing 1,2-pentanediol as an antibacterial component, there are cases where the warmth sustaining effect is impaired, and there is a case where the relaxation imparting effect cannot be sufficiently obtained. That is, it can be said that further improvement of the effect by improvement of such a technique has been desired.

  On the other hand, a gel cosmetic containing 1) a carboxyvinyl polymer which may be alkyl-modified and / or a salt thereof, 2) 90% by mass of a polyhydric alcohol, and 3) menthol and / or glyceryl monomenthyl ether. In the above, as the polyhydric alcohol, 10 to 30% by mass of polyethylene glycol having fluidity under the conditions of 1 atm and 25 ° C., and 1,3-butanediol and / or dipropylene glycol as the antibacterial polyhydric alcohol are 5 to 5. A cosmetic containing 40% by mass is not yet known, and it is not known that a cosmetic having such a composition has the above-mentioned properties.

JP 2002-33842 A Japanese Patent Laid-Open No. 2003-300839 JP 2006-117610 A

  The present invention has been made under such circumstances, and the antiseptic effect in warm gel cosmetics is replaced with an antibacterial polyhydric alcohol such as 1,2-pentanediol, and such an antibacterial polymorph. It is an object of the present invention to further develop a technology for supplementing the warmth-imparting effect impaired by the addition of a monohydric alcohol with the addition of menthol or glyceryl monomenthyl ether, and to provide a technology for enhancing the warmth-sensing effect.

In view of such circumstances, the present inventors replaced the antiseptic effect in warm gel cosmetics with antibacterial polyhydric alcohols such as 1,2-pentanediol, and the antibacterial polyhydric alcohols. As a result of earnest research efforts to further develop technology that supplements the warmth-imparting effect impaired by the addition of menthol with the addition of menthol and glyceryl monomenthyl ether, and seeks a technology that enhances the warmth effect 1) Alkyl modification A gel-like cosmetic containing a carboxyvinyl polymer and / or a salt thereof that may be prepared, 2) 90% by mass of a polyhydric alcohol, and 3) menthol and / or glyceryl monomenthyl ether, 10-30% by mass of polyethylene glycol having fluidity under conditions of 1 atm and 25 ° C., and 1,3-butane as an antibacterial polyhydric alcohol By adopting ol and / or dipropylene glycol structure containing 5 to 40 mass%, it found that improvement in the warming properties may pear, which resulted in the invention completed. That is, the present invention is as follows.
<1> Gel-like makeup containing 1) a carboxyvinyl polymer which may be alkyl-modified and / or a salt thereof, 2) 90% by weight of a polyhydric alcohol, and 3) menthol and / or glyceryl monomenthyl ether In the composition, 5 to 30 mass% of polyethylene glycol having fluidity under the condition of 1 atm and 25 ° C. as the polyhydric alcohol, and 5 to 1,3-butanediol and / or dipropylene glycol as the antibacterial polyhydric alcohol. Cosmetics characterized by containing -40 mass%.
<2> The cosmetic according to <1>, further comprising a pepper extract.
<3> The cosmetic according to <1> or <2>, characterized by not containing parabens.
<4> The cosmetic according to any one of <1> to <3>, wherein the cosmetic is a massage cosmetic that imparts a warm feeling.

  According to the present invention, the antiseptic effect in warm gel cosmetics is replaced with antibacterial polyhydric alcohols such as 1,2-pentanediol, and the warmth lost by the addition of such antibacterial polyhydric alcohols. Technology for supplementing the imparting effect with the addition of menthol or glyceryl monomenthyl ether can be further developed to enhance the warming effect.

<1> Carboxyvinyl polymer which may be alkyl-modified and / or salt thereof The cosmetic of the present invention is characterized by containing a carboxyvinyl polymer which may be alkyl-modified and / or a salt thereof as an essential component. To do. As the carboxyvinyl polymer, it is only necessary to use a polymer used as a thickener in cosmetics. As the alkyl-modified carboxyvinyl polymer, acrylic acid esterified with an alkyl group having 10 to 30 carbon atoms is used. A copolymer of methacrylic acid and acrylic acid or methacrylic acid can be preferably exemplified, and the copolymer may partially have a crosslinked structure with divinyl ether or the like. Among such alkyl-modified carboxyvinyl polymers, those already marketed as cosmetic raw materials exist, and such commercial products can be purchased and used. Preferred examples of such commercially available products include “Pemlen TR-1”, “Pemlen TR-2”, “Carbopol 1382” and the like commercially available from Goodrich. Particularly preferred are ordinary carboxyvinyl polymers that are not alkyl modified. Examples of these salts include alkali metal salts such as sodium salts and potassium salts, alkaline earth metal salts such as calcium and magnesium, organic amine salts such as ammonium salts, triethanolamine salts and triethylamine salts, and lysine salts. Preferred examples include basic amino acid salts such as arginine salt. Particularly preferred is a salt of triethanolamine, which is a base that dissolves in polyhydric alcohols. In the cosmetic of the present invention, the carboxyvinyl polymer which may be alkyl-modified and / or a salt thereof may contain only one species or a combination of two or more species. In the cosmetic of the present invention, the preferred content of the alkyl-modified carboxyvinyl polymer and / or the salt thereof is 0.05 to 1% by mass, more preferably 0.1 to 0.00%. 7% by mass.

<2> Menthol and / or glyceryl monomenthyl ether, which are essential components of the cosmetic composition of the present invention. The cosmetic composition of the present invention contains menthol and / or glyceryl monomenthyl ether as an essential component. This component enhances the warm feeling caused by the heat of hydration generated by the polyhydric alcohol containing polyethylene glycol which is liquid at 1 atm and 25 ° C., which is an essential component, and has a function of making the living body feel as a pleasant and very warm stimulus. Have. In order to exert such an action, the component is preferably contained in the cosmetic in an amount of 0.1 to 2% by mass, more preferably 0.2 to 1% by mass. This is because if the amount is too small, the sensitization effect may not be obtained, and if the amount is too large, the warmth may be exceeded and a sense of irritation may be felt. As a particularly preferred form, there can be exemplified a form containing only glyceryl monomenthyl ether which is not so great in warm sensitization but is excellent in sustainability of sensitization.

<3> Polyhydric alcohol which is an essential component of the cosmetic composition of the present invention The cosmetic composition of the present invention contains 90 mass% or more, more preferably 95 mass% or more of a polyhydric alcohol as an essential component. As an antibacterial polyhydric alcohol, 1,3-butanediol and / or dipropylene are 10 to 30% by mass, more preferably 15 to 25% by mass of polyethylene glycol having fluidity at 1 atm and 25 ° C. It is characterized by containing 5 to 40% by mass of glycol, more preferably 10 to 30% by mass. In the cosmetics of the present invention, polyhydric alcohols other than polyethylene glycol, 1,3-butanediol and dipropylene glycol having fluidity under conditions of 1 atm and 25 ° C are glycerin, diglycerin, and 1 atm at 25 ° C. Polyethylene glycol, polypropylene glycol, maltitol, sorbitol and the like that do not have fluidity can be suitably exemplified, but it is particularly preferable to select glycerin. This is because the heat of hydration of glycerin is suitable for realizing comfort.

  The polyethylene glycol having fluidity under the condition of 1 atm and 25 ° C. is preferably from 200 to 800, particularly preferably from 300 to 600, in terms of average molecular weight. This is because the warmth imparting effect is excellent.

  The inclusion of 1,3-butanediol and / or dipropylene glycol as the antibacterial polyhydric alcohol is intended to maintain antibacterial properties without impairing the warmth imparting effect. Here, 1,3-butanediol is a component having a characteristic that mainly has an antibacterial effect and is subordinate to a thermal effect, and dipropylene glycol is a component having a characteristic that mainly has a thermal effect and is subordinate to an antibacterial effect. It is preferable to use both of these in combination, and in this combination, the mixing ratio is preferably the mass of 1,3-butanediol: the mass of dipropylene glycol = 3: 1 to 1: 3.

  By adopting such a configuration, the warmth imparting effect is improved by increasing the initial temperature and lengthening the warmth imparting time. Further, even in the presence of a warming stimulus or a chemical stimulus such as menthol, the presence of parabens such as butylparaben is not required, so that it can be used comfortably without causing an increase in stinging. Thereby, a remarkable relaxation effect can be obtained.

<4> Cosmetics of this invention The cosmetics of this invention contain the said essential component, and are gel shape, It is characterized by the above-mentioned. Moreover, as a result of adopting such a configuration, it has excellent warmth imparting properties. Since the cosmetic of the present invention can be spread with almost no change in the coefficient of friction in the spreadability, it can be used as a cosmetic medium for the treatment in esthetic treatments for relaxation purposes. Particularly preferred. Furthermore, since it also has a solvent effect due to polyhydric alcohol, it has a cleansing function while being a massage medium. Since the cleansing function exists to a sufficient extent as a cleansing fee, it can be used only for cleansing purposes.

  Hereinafter, the present invention will be described in more detail with reference to examples.

According to the prescription shown below, the transparent gel cosmetics which are the cosmetics of this invention were created. That is, the ingredient (a) was uniformly stirred, and the ingredient (b) was gradually added to the mixture under stirring to form a gel, whereby the cosmetic 1 according to the present invention was obtained. In the same manner, cosmetic 3 was prepared by replacing glycerin monomenthyl ether of cosmetic 1 with menthol and replacing cosmetic 2 with capsicum extract of cosmetic 1 with glycerin.

Comparative example

Comparative Example 1 in which polyethylene glycol 400 of cosmetic 1 is substituted with glycerin, Comparative Example 2 in which 1,3-butanediol and dipropylene glycol are substituted with glycerin, Comparative Example 3 in which glycerin monomenthyl ether is substituted with glycerin, cosmetic Comparative Example 4 was also prepared in which 1,3-butanediol and dipropylene glycol of 1 were substituted with butylparaben.

<Test Example 1>
Using five female subjects, cosmetic treatments 1 to 3 and Comparative Examples 1 to 4 are performed for esthetic treatment (facial massage) for 5 minutes. Skin temperature immediately before treatment, skin temperature immediately after treatment, 5 after treatment Minute skin temperature was measured with a thermocouple thermometer, (skin temperature after treatment-skin temperature just before treatment) / skin temperature just before treatment × 100, immediately after application, rate of increase in skin temperature 5 minutes after application ( %) Was calculated. The results are shown in Table 2. From this result, it can be seen that the cosmetics 1 to 3 of the present invention have superior temperature rise characteristics as compared with the comparative example, and the degree of temperature decrease was small even 5 minutes after the treatment.

<Test Example 2>
In five female subjects, the presence or absence of warm feeling was evaluated by the following five points. The results are shown in Table 3.
1. Real feeling is high (5 points). 2. Slightly high feeling (4 points); There is a real feeling (3 points),
4). 4. There is almost no real feeling (2 points). No real feeling (1 point)
The lower the score, the lower the actual feeling of warmth.

From the results in Table 3, it was revealed that the cosmetic of the present invention has a noticeable warm feeling.

<Test Example 3>
Cosmetics 1 to 3 and Comparative Examples 1 to 4 were examined for antibacterial properties against fungi (Aspergillus niger), which are less effective for preservatives. That is, as the medium, SDA medium was used. In the method, 0.1 ml of the sample was smeared on the plate medium and inoculated with a platinum loop, and the number of colonies was counted on the 1st and 3rd day after inoculation. The results are shown in Table 4. From this, it can be seen that Cosmetics 1 to 3 which are the cosmetics of the present invention are superior in antiseptic power as compared with Comparative Example 2. Moreover, since the comparative examples 1 and 3 contained 3-butanediol and / or dipropylene glycol, the antiseptic power was comparable to that of the present invention. Moreover, since the comparative example 4 also contains butylparaben, the antiseptic power showed the high effect similarly to the cosmetics 1-3.

<Stinging test>
A sting test was performed on the cosmetic (Comparative Example 5) in which 1,3-butanediol and dipropylene glycol in Comparative Example 4 and Cosmetic 2 were substituted with glycerin. In other words, in the cosmetics, using 5 panelists who are likely to feel transient irritation, they told me that they would like to be taught when irritation was felt in a state where their vision was blocked. It was lightly touched and included to test whether irritation was felt. As a result, in Comparative Examples 4 and 5 containing parabens, there was a complaint of irritation in any of the panelists. However, there was no complaint of irritation even when the sting test was performed on the cosmetics 1 to 3 of the present invention.

From the above results, an increase in skin temperature is recognized by the treatment using the cosmetic of the present invention, and it is clear that the sense of warmth is high, antiseptic power is high without adding paraben, and when paraben is contained. It was proved that there was less irritation than that.

INDUSTRIAL APPLICABILITY The present invention can be applied to cosmetics that have an antiseptic effect in warm gel cosmetics and supplement the warming-imparting effect that has been impaired by the addition of antibacterial polyhydric alcohols to enhance the warming effect.
